Abstract
A method of detecting the presence or absence of a sealant applied to a textile graft includes the steps of: providing a textile graft having a first surface and an opposed second surface; providing a water soluble masking agent; applying the water soluble masking agent to at least a portion of the first surface of the textile graft; providing a sealant solution; providing a visual indicator; applying the water insoluble sealing agent and the visual indicator to the second surface of the textile graft; and removing the water soluble masking agent after the step of applying sealing solution. The second surface has visual indication of the visual indicator and the first surface is substantially free of visual indication of the visual indicator. An implantable textile graft includes the selectively applied visual indicator.
